Port 67 and DHCP settings

I’m trying to install Pi-hole on ZimaOS v1.3.2-beta2. But port 67 is unavailable:

Port 67 seems to be DHCP. Is there a DHCP server running on ZimaOS by default?

I also cannot access the DHCP settings:

The dots are not clickable. Nothing happens.

The issue you’re encountering is due to port 67 being occupied by dnsmasq. dnsmasq is primarily used to assign IP addresses to ZVM instances.

To resolve this, you can check which service is using port 67 by running the following command:

netstat -tulnp | grep :67

If dnsmasq is the service occupying the port, you can stop it using:

killall -9 dnsmasq

This will release port 67, allowing your Docker application to use it. However, please note that stopping dnsmasq will cause ZVM’s network functionality to become unavailable.

Let me know if you need further assistance!
